HINGE.

Specification of Letters Patent.

Patented (5a. 29,1912.

Application filed June 15, 1912. Serial No. 703,834.

To all whom it may concern:

Be it known that I, JAMES LOUGHREN, a citizen of the United States, and resident of Arlington, city of Cranston, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Hinges, of which the following is a specification.

This invention relates to hinges and has for its object to provide a hinge of comparatively simple and inexpensive construction to which an adjustable friction device is applied for yieldably retaining the door or other device, to which the hinge is attached, in any desired position.

With these and other objects in View, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

Of the accompanying drawings: Figure 1-is a front elevation of my improved hinge showing the knuckles of each leaf in section. Fig. 2is a section on line 2-2 of Fig. 1 showing a portion of each leaf and the square shape of the center hole in one of theknuckles. Fig. 8is a top or end View showing a portion of both of the hinge leaves and illustrating the ratchet teeth and pawl arrangement for securing the friction nut in the desired position on the outer end of one of the knuckles. Fig. 4-is the same as Fig. 3 with the nut and pawl removed. Fig. 5is an enlarged side elevation illustrating the pawl and ratchet mechanism for securing the nut in adjusted position. Fig. 6-is a detail of the pivot pintle removed. Fig. 7is a sectional view of the filler sleeve in which a portion of the pintle has its bearing. Fig. 8-is a modification showing a locking pin for retaining the nut in the desired position on the end of the knuckle.

Referring to the drawing, the hinge comprises a pair of members or leaves 10 and 11, the leaf 10 being provided with two enlarged spaced apart portions or knuckles 12 and 13, one at either edge thereof, the same being adapted to receive between them a corresponding knuckle 14: formed on the leaf 11 to provide conjointly with the knuckles 12 and 18 a pintle receiving barrel having a central longitudinal bore designed to receive a pivoting bolt or pintle 15 for pivotally connecting the leaves together. The bore 16 in the knuckle 1 1 is preferably square to receive the correspondingly squared portion 17 on the pintle. The bore 18 in knuckle 12 is formed large enough to permit the squared portion 17 to pass there through into the bore of knuckle 14 and this bore is then reduced by the bushing or sleeve 19 to fit the upper portion 20 of the pintle. Both ends of this pintle are threaded as at 21 and 22 for the reception 'of nuts 23-24. A raised portion 25 is provided on the outer face of knuckle 13 to engage the side of nut 23 and prevent it from turning on. said face, in other words, to cause the nut to rotate or move with the knuckle and not rotate with the bolt when turned by the movement of the other leaf. At the opposite end of this leaf the outer face of'knuckle 12 is shown as being provided with a plurality of ratchet teeth 26, see Figs. 3, 4 and 5, which are adapted to be engaged by the pawl 27 mounted by the pin 28 on the nut 24., whereby this nut 24 may be set up or tightened against the end of this knuckle with sufiicient force to provide the desired friction on the threaded portion of the pintle so that when the leaves 10 and 11 receive a relative movement the squared portion in the leaf 11 causes the pintle to turn with that leaf and rotate in the bore of the other leaf, therefore if the nuts 23 and 24; are held against rotation the threaded portions of this spindle are caused to rotate in said nuts and when the nuts are set up against the ends of the knuckles 12 and 13 sufficient friction may be caused in the threaded portion to provide the desired resistance to yieldingly hold the hinge in any position. As the threads on the opposite ends of the spindle are both right handed and of the same pitch the distance between the nuts remain unchanged as the spindle'rotates therein, which rotation causes the pintle to receive a slight endwise movement through'said nuts due to the pitch of the threads. To remove the friction it is only necessary to raise the pawl and turn the nut 24: backward.

I do not wish to be restricted to the use of a ratchet and pawl mechanism for retaining the nut in the desired position as a pin 29, see Fig. 8, may project from a corresponding hole in the knuckle 12 to engage any face of the many sided nut 30 and so retain it in position to effect the desired degree of friction, or any other suitable means may be employed for this purpose. Neither do I wish to be restricted to the forming of the pintle with a square in one of the knuckles having knuckles adapted to conjointly form a barrel provided With a longitudinal bore, a pivot pintle extending through said' bore, means for preventing rotation of said pintle in the knuckles of one leaf, and locked nuts for frictionally' controlling its rotation inthe knuckles of'the other l'eafi 2. A hinge comprising a pair of leaves having knuckles adapted to conjoint-1y form a. barrel provided with a longitudinal bore, a pivot pintle extending through said bore, means for preventingrotation of said pintle in the knuckles of one lea-f, nuts on the ends of said pintle, for frictionally controlling its rotation in the knuckles of the other leaf,

and. means for locking said nuts in position to maintain the desired degree of friction.

3. A hinge comprlslng a pair of leaves havmg knuckles adapted to con o1ntly form a barrel provided With a longitudinal bore, a

pivot pintle extending through said bore, a portion of said pintle being square to loosely fit into a corresponding portion in the bore of the knuckle of one leaf, a nut on each end of said pintle for frietionally controlling its rotation in the knuckles of the other leaf, and means for locking said nuts in position to maintain the desired degree of friction.

In testimony whereof I aiiix my signature in. presence of'two Witnesses.
